Transformers for JSC Russian Railway Research Institute (VNIIZhT)

Recently have been energized with positive result the 6 units supplied to JSC Russian Railway Research Institute, installed in the transformer substation of the experimental loop of  "Shcherbinka", a small city near Moscow.
The scope of supply consists of the following oil immersed transformers:

- no.2 Single-phase regulating autotransformers with Power rating of 12500 / 12500 / 900 kVA, radiator tank and ONAF cooling. The related voltage ratio is:  27.5 kV / 15150 ÷31617 (17 switching positions)  / 9000 V obtained by OLTC.

                              

- no.1 Single-phase transformer with Power rating of 3300 kVA, radiator tank and ONAN cooling. Special secondary exits have been made by flat copper busbars on the lateral side of the tank. The related voltage ratio is: 22 kV / 160 (40) V. 

  

- no.1 Single-phase transformer with Power rating of 3300 kVA, corrugated tank with ONAN cooling. The related voltage ratio is: 22 kV / 3700 - 1850 V.  

- no.2 Single-phase transformers with Power rating of 400 kVA, corrugated tank and ONAN cooling. The related voltage ratio is: 9 kV / 320 V.

JSC Railway Research Institute was founded in 1918 and since 2008 it is an affiliated Company of JSC " Russian Railways".

It is the largest scientific center in the field of design and research (20 divisions): the total number of employees is over 1700 people, including 34 Academic Doctors and 154 Candidates of Sciences focused on the securing of infrastructures / operations and on the creation of new technical equipment and transport technologies.

In VNIIZHT is possible to conduct all spectrum of certification tests: it has the world’s first of its kind test facility for permanent way designs with loads of 300-350 million tons per year, facility for the conduction of rolling stock tests at speeds of up to 220 km/h and tests of elements / units at loads of up to 500 tons. Laboratory tests include also static, dynamic and cycle tests. Field tests executed on the test track include passenger rolling stock tests at speeds of up to 120 km/h, freight rolling stock tests at speeds of up to 90 km/h and intensity of goods traffic is 300-350 million t/km per km gross per year. Also tests on regular railway lines are conducted.

Considering that railway industry is currently one of the Russian economy's most dynamic market segments, SEA is really proud to be part of the projects where these research activities are currently carried out.
